石嘴山電梯維修保養人員的工作內容
隨著科技的進步,電梯技術水平不斷提高,其運行的可靠性明顯加大。在維修保養中,一些比較典型的停梯故障需要及時排出。
1、斷相引起停梯
當三(san)相(xiang)(xiang)電(dian)(dian)(dian)(dian)源出(chu)現斷(duan)相(xiang)(xiang)時(shi),相(xiang)(xiang)序繼(ji)電(dian)(dian)(dian)(dian)器動作切斷(duan)a全回路(lu),使電(dian)(dian)(dian)(dian)梯(ti)停(ting)止運(yun)行(xing)。這種故障多出(chu)在繼(ji)電(dian)(dian)(dian)(dian)器邏輯控制的電(dian)(dian)(dian)(dian)梯(ti),因為(wei)是老(lao)式電(dian)(dian)(dian)(dian)梯(ti),電(dian)(dian)(dian)(dian)源開(kai)關多為(wei)閘刀式,電(dian)(dian)(dian)(dian)源經過j限(xian)開(kai)關,再(zai)送(song)至(zhi)電(dian)(dian)(dian)(dian)梯(ti)控制柜、電(dian)(dian)(dian)(dian)源流經的兩個開(kai)關,共六根保(bao)險(xian)絲(si)(si)。電(dian)(dian)(dian)(dian)梯(ti)運(yun)行(xing)、起動,電(dian)(dian)(dian)(dian)流都很大。經過一(yi)段(duan)時(shi)間運(yun)行(xing),如維保(bao)人員不及時(shi)檢(jian)查,保(bao)險(xian)絲(si)(si)與(yu)螺(luo)絲(si)(si)連接處易燒斷(duan),電(dian)(dian)(dian)(dian)梯(ti)斷(duan)相(xiang)(xiang),引起停(ting)梯(ti),輕則關人,重則發(fa)生事故。
主要預防措施:
①保養人員要經常巡視檢查,發現(xian)(xian)可疑之處,及時(shi)修理,出現(xian)(xian)發燙、打火花諸類情形(xing)應立即更換。
②建議用戶將閘刀開(kai)關更換為相當容(rong)量的(de)空氣開(kai)關。
③現在設計(ji)的電(dian)梯都沒有電(dian)源j限開關(guan),筆者認為,可(ke)以就a全(quan)回路略作改動(dong),即(ji)加裝上、下j限電(dian)氣開關(guan)串聯在a全(quan)回路中,拆(chai)除原(yuan)j限開關(guan)。
2、漲繩輪開關斷開引起停梯
像曳(ye)引繩(sheng)(sheng)一樣,限速(su)器繩(sheng)(sheng)同樣會在(zai)使用(yong)過程中伸長。由(you)于底坑漲繩(sheng)(sheng)輪(lun)重(zhong)錘的作用(yong),漲繩(sheng)(sheng)輪(lun)開關打板偏移,直到(dao)斷開開關導致停梯。
對于電梯安裝的新裝電梯,電梯安裝人員須每月(yue)檢查一(yi)(yi)次,運(yun)行(xing)一(yi)(yi)年以后,三個月(yue)檢查一(yi)(yi)次,如此(ci)即可防患于(yu)未然。由(you)于(yu)廳門密封不(bu)嚴(yan),井道有墻洞等(deng)各種原因,老鼠竄入(ru)(ru)井道時(shi)有的(de)會摔(shuai)死,有的(de)掉入(ru)(ru)底坑(keng)因想(xiang)方設(she)法逃出竄入(ru)(ru)繩輪而卡入(ru)(ru)其中,電梯向下(xia)運(yun)行(xing)導致a全鉗開關動作,有的(de)限速器開關也一(yi)(yi)起聯動。
